深潜者（Deep Ones）是霍华德·菲利普·洛夫克拉夫特创建的克苏鲁神话中出现的虚构生物，最早出现在其于1931年发表的短篇小说《印斯茅斯疑云》（The Shadow Over Innsmouth）中，但在其更早的作品《达贡》（Dagon，1917年）中已有这些生物的雏形。与深潜者有关的题材不断地被引用和再创作，是克苏鲁神话体系中影响重大的元素之一。
Deep Ones is a fictional creature that appeared in the Cthulhu mythology created by Howard Philip Lovecraft. It first appeared in his short story "The Shadow of Innsmouth" published in 1931. Over Innsmouth), but there are prototypes of these creatures in his earlier work "Dagon" (Dagon, 1917). Themes related to deep divers are constantly quoted and recreated, which is one of the most influential elements in the Cthulhu mythology system.
深潜者是住在海底的类人种族，外观为鱼头人身，身上的主色是灰绿色，但有白色的腹部，四肢的指间有蹼，身上覆有鳞片，眼睛如鱼眼一般突出且不会合上，颈部有鳃，在陆上行动时会用两脚或四肢蛙跳跃进，在相关典籍中被描述为像蛙的鱼或像鱼的蛙，身上带有浓厚的鱼腥味，也有不少完全脱离人形。虽然外观看似与人类有显著的差异，似乎没有高智慧的表征，但深潜者是除非遭杀害否则就会永生不死的高智慧种族，且会利用鱼获和黄金与海岛上的住民交易活人以当祭品。他们信仰并效忠于父神达贡和母神海德拉（两名较小的旧日支配者，也有可能仅仅是特别巨大的深潜者），克苏鲁也是他们的信仰对象。
Deep divers are a humanoid race that lives on the seabed. They have a fish head and a human body. The main color of the body is gray-green, but it has a white abdomen. There are webbed fingers on the limbs. The body is covered with scales and the eyes protrude like fish eyes. And it will not close, there are gills on the neck, and it will jump in with two feet or four limbs when it moves on land. It is described in related classics as a frog-like fish or a fish-like frog, with a strong fishy smell on its body , There are also many who are completely out of human form. Although the appearance seems to be significantly different from that of humans, and there does not seem to be a sign of high intelligence, the deep divers are a highly intelligent race that will live forever unless they are killed, and they will use fish and gold to trade with the residents of the island. People are used as sacrifices. They believe in and are loyal to the father god Dagon and the mother god Hydra (two smaller Old Ones, or they may just be particularly huge deep ones), and Cthulhu is also the object of their beliefs.
